fix(telegram): restore model-switch success path + author map

The cherry-picked PR over-indented the edit_message_text block for
the mm: (model selected → switch) success path so the confirmation
edit lived inside the preceding 'except Exception as exc' branch and
only fired when the callback raised. Dedent the try/except back to
12-space indent so it runs after the callback succeeds, restoring
the original flow that removes the inline buttons and shows the
'Switched to ...' confirmation.

Add a regression test (test_model_selected_edits_message_on_success)
that asserts edit_message_text is awaited and the result text is
routed through format_message (MARKDOWN_V2 + backtick survival).

Add phuongvm to scripts/release.py AUTHOR_MAP.
